What's wrong with my speaker?

almost certainly a broken voice coil assembly.  Replace.
Vienna drivers are costly!  But the speakers are great. I have Mahlers ....

There is an app for the phone that will measure decibels

depending on the cost of a new driver contact Bill Legall at Miller Sound in PA for his advice.

Thanks for everyone’s input and advice. I rotated the driver, and it only improved the crackling only marginally if at all. It was worth a try, though.


@bigkidz does Miller Sound sell used Vienna Acoustics parts or is Bill Legall good at fixing these types of issues? I checked Miller Sound's website, and Vienna Acoustics is not on their list of brands that they service. Thanks for the input.

Wonder if you could take it to a dealer and they could replace the driver or perhaps offer a solution.  Hope this problem does not happen to me.  This may be a difficult thing to repair during the Trump virus.
